SPECIFICATION forming part of Letters Patent o; 7405735, dated October 6, 1963-. Application nea January 2, 1l-ios. A serial No. 137,394'. (No man To all whom it may concern:

Be it known that I, GEORGE W. BLAKE, a citizen of the United States, residing at Natrona, in the county of Allegheny and State of Pennsylvania, have` invented a new and useful Improvement inA Filling-Machines, of Which improvement the following is a specilication. K

This invention relates to an improved filling-machine, and it relates more particularly to that class employed for canning caustic alkali and the like; and it consists in the certain details of construction and combination of parts, as Will be fully described hereinafter.

flhe object of the present invention is to provide means that will prevent the material from sticking or clogging, this being prevented by the novel means of agitation.

Another object of the invention is to provide an automatic measuring and filling device that will deliver the requisite amount of material into each can or receptacle.

The invention also contemplates to provide a device of this character1 Which Will be eX- tremely simple in construction, strong, durable, comparatively inexpensive to manufacture, and highly efficient in its use.

Vith the above and other objects in view I Will describe the inventionV in detail, reference being had to the accompanying drawings, in Whichy Figure 1 isa side elevation of my improved filling-machine, the same being constructed and arranged in accordance with my invention. p Fig. 2 is a front elevation of the same, a part of which is shown in section. Fig. 3 is a sectional plan view, the said section being taken on the line Y Y of Fig. 2. Fig. a is a vertical sectional side elevation of the machine, the section being taken on the rline X X of Fig. 2. of the measuring-table, showing the gages and front plates removed therefrom, valso showing the construction of the measuringchambers. Fig. 6 is a similar view of the divided front-plate detached from the measuring-table. Fig. 7 is a side central sectional elevation of a portion of the machine, the section being taken through one of the measuring-chambers. Fig. 3 is a perspective view of one of the adjustable gages used to regulate the capacity of the measuring-chambers.

Fig. 5 is a perspective View Fig. 9 is a perspective vievv of the nut by 'means of which the measuring-gages may be set in the desired position. Fig. l0 is a perspective view ofaportion of the feeding frame and rack, together with the feed stop or release. Fig. 11 is a side sectional elevation of the said feed stop Aor release. I

To put my invention into practice, and thereby provide a machine for filling cans with caustic alkali or like substance, I provide a frame 1, of a suitable size and form of construction, and mount therein, by means of guide-plate 3, a second or vibrating frame 2. Said frame is capable of a limited vertical Wheels 5, mounted on a shaft 4, being brought in contact with pieces 6, let into the said frame immediately above the said toothed Wheels, the movement being regulated by formed integral with the stationary frame 1 and engaging with the lower ends of the vi- -brating frame 2. p These Vtoothed Wheels 5 and regulating-screws 9 are arranged at either side of the machine and the said Wheels operated by means of sprocket-WheelslO, connected by chain belts l1 to similar Wheels 13, mounted on a power-shaft 12, arranged in suitable bearings formed at the rear end of the vibrating frame 2 in a manner that the shaft 4 and its connected parts is given a continuous rotary movement. f Mounted in bearings 19, formed on the inner side of the stationary frame l, are two shafts 17 and 17', each of which is provided with sprocket- Wheels 24 and 24, connected the one With the other by a chain belt, and the saidshafts driven by sprocket connections 22 and 23 from the shaft e below. Fach of these countershafts 17 and 17 is fitted with tivo cams 1S land 13', adapted to give a slight vertical movement to a'set of lifting-bars 20, with which they are brought in contact during the rotary movement of the said cams. These liftthe one parallel to the other, and operate through slots 20, Fig. 3, formed in a table 13, rigidly Xed on the top of the stationary frame 1 in a manner that when the lift-bars face will be slightly above the level'of the said table 13. Arranged on suitably-fixed vibrating movement, produced by toothedV large set-screws 9, operating through bosses 3,

`bars 2O are arranged in a horizontal position,l

IOO

20-are in an elevated position their top surslide-bars 46, supported in bearings 47 beneath the table 13, is a feed-frame consisting of a T-shaped casting, (see Fig. 10,) formed with a semicircular guide 2S, operating in a groove formed in the under side of the table 13, and also with a bore 29, in which guide a rod 29X, Fig. 4, is placed. The head-piece 26 is fitted with adjustable upwardly-extending lugs or feed-dogs 29, held in the desired position by bolts 27, operating through slots, and the said dogs passing through slots 25, Fig. 3, formed in the table 13, and extending in the direction of the length of the same. Formed on the under side of this above-de scribed feed-frame is a rack 30, which in connection with a feed-arm 39, connected to the shaft 17 below, provides means for feeding the said frame 26 forward one notch at a time or a distance equal to the diameter of the can 16 operated upon. This feeding-frame is also fitted With a stop, (see Figs. 10 and 11,) consisting of a tube 33, in which is a bolt 31, the said tube being rigidly connected to the headpiece 26 and the bolt 31 projecting through the same to engage with a rack 76, formed on the under side of the table 13. This bolt is held in position by means of a key or bar35, passing througha slot 32 in the said bolt and also through a slot 34, formed through the side walls of the tube. Beneath the bolt 31 is a spiral spring 37, held in position by a cap 38, placed on the lower end of the tube, the said spring used to keep the bolt thrust forward and in contact with the table-rack above mentioned. The bar 35 is formed with a tapered or enlarged portion and a head 36, which, when the said enlarged portion is moved forward into the slots 32 and 34, will draw the bolt 31 within the tube, thereby disengaging the said bolt from the table-rack 76. This movement of the bar 35 is brought about by the head 36 thereof coming in contact with a stationary piece 13 beneath the table 13, Figs. 1 and 4, and located at apoint at the end of the feed-frame stroke. The said frame is recovered or brought back to its original position by means of a weight 41, attached to a rope 42, the other en'd of which is connected to front en d of the rack-bar 30. Secured at either side of the table 13 are anglebars 14, which act as guides which support and guide the tray 15, containing the empty cans 16 during the operation of filling the same.

Arranged upon the top of the vibrating frame 2 is a hopper 50, in which a shaft 53, provided with agitators 54, is operated, the said shaft receiving its motion from sprocket- Wheels 72 and 72, connected theone with the other by a chain belt 7 2X. This hopper 50 is formed with an opening 51 at the base,througl1 which the material to be canned passes into a measuring-table arranged in slides beneath. This measuring-table consists of a plate 59, (see Figs. 5, 6, 7, 8, and 9,) mounted in between guide members 57 X, placed at each side of the vibrating frame, and is operated back and forward beneath the hopper 50 by means of connecting-rods 5S, attached to integral studs 57, formed with the plate, and to crankpins 57', attached to the sprocket-wheels 13/ on the drive-shaft 12. This plate 59 is divided into a series of compartments to form measuring-chambers 60, the sides of which are at angles to the sides of the plate. These measuring-chambers 60 are open at the top, bottom, and front and separated one from the other by partitions 67, and between each partition is placed a gage formed from a single piece of metal 61, having an outwardly-projecting flange and a lug 62 with threaded socket 65 and is adapted to be moved toward or away from the rear wall of the compartments 60 by means of a nut 64, held in position by a divided plate 63, engaging a groove 64, the said plate being attached by bolts to the body of the table 59. The nut 64 is free to turn and is formed with a threaded bore, which in connection with a threaded shaft 65, operating therein and in the threaded bore 61 of the gage, affords a means of moving thelatter to regulate the exact quantity of material received by the measuring-chamber. These measuring-chambers operate between an upper plate 60'and lower plate 69, the latter having openings 70, registering with the said chambers. The bottom of this last-mentioned plate 69 is fitted with a soft-rubber pad 71, against which the mouths of the cans are pressed while receiving the contents of the measuring-chambers.

In operation the material to be canned is fed into the hopper 50 and passes down through the opening 5l at the base of the same when the measuring-chambers 60 are brought beneath by the movement of the table 59, and the said material being agitated. by both the vibration of the frame 2 and paddles 54 the same is prevented from packing. Each of the measuring-chambers receiving the material will be filled and by a further forward movement of the table will deposit their contents into the discharge-openings 70, formed in the plate 69.

While the above-described operation is taking place, the shafts 17 and 17 being in motion, the cams 1S lift the bars 20, thereby pressing one row of cans tightly against the rubber 7l and receive the contents of the measuring-chambers above. )Vhen this has been accomplished, the bars are lowered and the feed-arm 39 engaged with one of the notches 30 to move the tray forward a dis- ICC ITO

tance equal to the diam eter of the cans, therev at the rear of the machine withdrawing the said bar brought against a lug or projection to release the bolt 3l to again engage with its rack.

Various slight modifications and changes may be made in the details of construction Without departing from the spirit of the invention. Therefore, I do not confine myself to the exact construction shown and described.
